Users / Mythtv corruption when recording with 2 or more tuners.

« on: October 11, 2010, 07:54:18 am »

Hello,

When recording (or viewing) 2 or more shows on different muliplexs all of the recordings will go green and pixelate. If you stop the additional recording straight away everything goes back to normal. If you leave the recordings going eventually the tuner card will crash with i2c_scan errors. At this point you need to turn off the core and turn it back on to have mythtv start to function again.

This only happens when the second (or third) tuner is used. If can record 2 shows on the same multiplex with one tuner fine. I have tested all tuners individually and they are fine. Following other posts about the i2c_scan errors it suggested that poor signal may have been the issue. I have excellent quality signal in the 50-60% strength range but I went out and bought a booster just in case. Now my signal is 70-80% but had no effect on my problem.

Mythbackend logs show no error. dmesg and /var/log/messages also show no error unless you let the problem proceed to a tuner crash. I don't know how to access mythfrontend's output in linuxmce.

My system details are below. Any help would be greatly appreciated. I have exhausted all the this forum and google have on the subject.


Core
AMD phenom x4
4GB DDR3
1x 80GB hdd (os)
1x 1TB pipeline hdd (data)
3x Winfast USB DTV GOLD tuners
2x Gigabit nic

MD
Asrock 330HT diskless

Software
Linuxmce 8.10 net install as per wiki. Latest updates.

Users / Re: CM11a module

I think in the future I may try to get CM15 support going, but they offer very little over a CM11A, and are much more expensive.

Is that future in progress?
The CM11 stopped production some time ago.
The CM12 (Usb CM11) Is currently in 'End of life' so one stocks are sold they too will be no more.

So its down the the CM15,

The is especially true due to the majority of Zwave devices either failing to comply with Australian Standards or failing to find a Distributor. So X10 for us it seems. At least for the moment.

Thank You

Dual tuners helps but not solves the problem.
This is what needs to be achieved.

minimum
4x free to air (DVBT) tuners (or 2  dual tuners)
2x DVBS
2x analogue capture (or tuners) for cable TV

This setup will be for a large household with multiple concurrent users and as you can see multiple TV sources.

Users / Simple Network Question

« on: May 06, 2008, 03:18:49 pm »

Hello,

I currently have a dedicated dhcp server (FreeBSD) which feed all my other machines my cable internet.
The setup is standard 1 eth port to the cable modem and another to the switch.

LMCE wants to be the server and I want to let it. My problem is that my cable point on the other side of the house to my aieral points.
Moving the points is not a simple or cheap task in this house. Running a network cable from the modem to the core's location is also not an option due to long length of the cable and poor output from the modem.

I am sure there is a simple solution out there I am just not doing well getting it.

Thank You.

Users / Need more tuners than PCI sliots

« on: May 06, 2008, 03:10:22 pm »

Hello,

I require more tuners than I have PCI slots. What would be the best solution to achieve this?
Can multiple USB tuners play well with multiple PCI ones?
Is there some way to slave another machine to the core?

I apologize if this information is easily found. I had no luck.

Thankyou.
